FIG. 8

SWIMMING POOL LIGHT SYSTEM CROSS-REFERENCE TO RELATED APPLICATION Formany years, certain types of swimming pools such as those installed inathletic clubs, country clubs and the like, especially those havingtiled sidewalls, have been provided with water-tight arrangements oflights in the sidewalls and/or bottom of such pools, below the waterlevels therein, in order to illuminate the pools at night. This isdesired in order to extend the hours within which pools of such type maybe utilized, notwithstanding the use of additional lights at levelsabove the pool, for nighttime use of the pool. Such illumination of theinterior of the pools renders swimming, diving, and other uses of thepool more pleasant under nighttime conditions than if the interior ofthe pool is not so illuminated. I

Construction of the types of pools referred to above is relativelyexpensive, particularly in comparison with many types of popular poolsinstalled at present in the yards adjacent individual homes, includingpools which are not only of the type installed in the ground but alsothose which are above ground. Many such pools simply comprise sidewallsformed from various types of sheet material, the pool-side surfaces ofwhich are covered by waterproof plastic sheeting such as vinyl sheetmaterial which, in addition, also usually is extended across the bottomsurface of the pool. Such bottom surfaces principally are formed bycompacted sand, especially in regard to the construction of so-calledin-the-ground pools. The installation of lights below the water level ofsuch pools has been undertaken heretofore but, in general, variousproblems are encountered such as maintaining the side of the poolwaterproof at the area in which the light is installed. Leakage is notinfrequently encountered under such circumstances so that, in general,providing pools of such type with illumination below the water level hasnot been entirely successful or popular. Maintenance also is difficult.

In the several attempts which have been made to provide pools withilluminating lights below the water level, supporting means have beenresorted to which, in the example shown in U.S. Pat. No. 3,090,489, inthe name of Smith, issued May 21, 1963, utilize a swimming pool ladderwhich extends into the pool. In this particular construction, thesidewall of the pool appears to be of a substantial type, such as oneformed from masonry, and therefore apparently being of expensive nature.Said light uses one of the side rails of the ladder as a conductor forcurrent to the light and the light is of a waterproof nature. This typeof mounting for a light restricts the position thereof and thereforeprovides only limited usefulness, and bulb exchange is difficult.

A more recent U.S. Pat. No. 3,456,103, in the name of Bond, issued July15, 1969, illustrates a waterproof enclosure adapted to be positionedbelow the water level of a swimming pool for purposes of containing apair of sealed-beam type electrical lights such as those used inheadlights of automobiles, and a conventional conduit pipe extendsupward therefrom and is secured fixedly to a handrail adjacent one sideof the pool. The handrail is supported by vertical posts which appear tobe of a permanent nature and the structure is largely concerned withrendering the light grounded electrically in the event either thehousing or the light bulbs are fractured in any way. Such light ispermanently installed at a fixed location and the support for the lightbulb is of a fixed nature and incapable of being mounted in a portablemanner.

There is a substantial demand at present for a relatively inexpensiveand'easily installed type of light for swimming pools which can beinstalled when the pool is constructed or, if desired, at a later date,which includes electric light bulb assemblies positioned within the poolbelow the water level thereof, for use in either above-the-ground orin-the-ground types. It is the principal purpose of the presentinvention to fulfill such a demand by proposing several embodiments oflight systems readily capable of fulfilling all reasonable expectationsof such type of lighting.

SUMMARY OF THE INVENTION The principal object of the present inventionis to provide a swimming pool light which includes a minimum number ofelements and, primarily, a base means which can be permanently attachedto the deck or apron anywhere along a pool edge but, in particular,under the diving board, said base means supporting preferably asubstantially L-shaped tube having a horizontal leg clamped by said basemember and a longer, substantially vertical let extending into the pooland having a light head with an electric light socket and bulbpositioned therein, said bulb being furnished current, preferably of avoltage substantially reduced below normal household voltage, which iscarried by insulated wire or conduit extending within the tube, beyondthe base means and interconnected to a source of such current, such asreduced by a transformer. Regular house current having a ground faultcircuit interrupter protection unit can also be used. Further, batterypower may be utilized.

It is another object of the invention to provide the base means with aseat which receives the normally horizontal leg of said L-shaped tubeand a readily removable clamping head detachably engaging said leg ofsaid tube when disposed in said seat to secure the other leg of the tubeand the light thereon in desired location relative to the side of apool, below the water level therein. The tube can also be keyed to saidsupport to prevent movement or rotation thereof relative to said seat.

It is a further object of this invention to provide an optional bracketat the under-water light head, to lend stability to and further supportsaid light head, if so desired. One part of this bracket is adapted tobe permanently anchored to the pool sidewall at light head level, withfolding wing type anchor screws, well nuts, or similar means insertedinto relatively small holes made through the vinyl liner and supportingpool side. Adequate rubber gaskets or similar sealing means attached tothe bracket or a part of the fastener contacting surface will preventleakage. lt is further proposed that the light head have a matingattached tongue which is slidable vertically to engage said permanentlyanchored sidewall bracket.

It is still a further object of the invention to include a voltagetransformer in the circuit for the light, preferably remotely locatedfrom the pool edge, said trans former being connected to a conventionalsource of household current and adapted to convert the same to a voltagesubstantially less than that of the household current, such as of theorder of 12 volts or the like, and supply such reduced voltage type ofcurrent to said light.

It is still a further object of the invention to use battery power,preferably of the more or less 12 volt range. A rechargeable andportable type battery is preferred for such use. The battery preferablyis to be located in an out-of-the-way location, such as under a divingboard or similar protected region.

One further object of the invention is to provide a quick detachableplug and socket means perferably adjacent the terminal end of the tubewhich is supported by the base means, whereby if the tube and lightassembly is removed for bulb replacement or maintenance, a quick andconvenient disconnect thereby is provided.

One of the most substantial objects of the invention is to provide alight for a swimming pool which is readily removable from the pool,especially to change a bulb, without draining the pool or providingelaborate means to otherwise effect such changing of the bulb withoutpool drainage. Removal of the lights readily for winter storage also isan added benefit and initial installation is simple.

Another object of this invention is to provide a means of installing anunderwater lighting system which is practical, easy to install and iseconomical for existing in-ground installations not presently havingunderwater lighting.

Details of the foregoing objects and of the invention, as well as otherobjects thereof, are set forth in the following specification andillustrated in the accompanying drawings comprising a part thereof.

DETAILED DESCRIPTION Referring to FIG. 1, one embodiment of lightingsystem is illustrated in side elevation relative to a fragmentarilyillustrated portion 10 of .a deck of a swimming pool. The deck 10 alsois intended to be illustrative of any suitable mounting surface adjacentthe side of a pool, for example. As shown in FIG. 1, the deck 10 alsohas a coping 12 connected thereto. In connection with the presentinvention, it is conceivable that the coping can have an upper surfaceextending away from the body 14 of the pool, which is confined by thesidewall and vinyl liner 16, a suitable distance to provide a supportfor the base means 18 of one embodiment of light system employing theprinciples of the present invention. Said base means comprise a basemember 20 which may be formed from any suitable material, such as bymolding, pressing sheet material between a pair of appropriate dies, orcasting within a form of appropriate size and configuration. By way ofspecific example, the base member may be cast from metal, preferablynon-corroding type such as bronze, aluminum, or stainless steel.Alternatively, the base member 20 may be die-cast from suitable metal,such as so-called white" metal, which essentially comprises zinc, orotherwise. If the base is a type, as describer hereinafter, to beattached to the deck or coping of the pool, it may be formed as asuitable shell, by stamping or casting, from appropriate metal orplastics.

In its preferred embodiment, the base member 20 is provided with a lowersurface 22 which is adapted to conform and be affixed to the uppersurface 24 of the deck 10 or coping 12, if the coping is of suitablewidth to accommodate base member 20. From FIG 2, it will be seen thatthe base member 20 may be provided with a central passage 26, ifdesired, or, as shown in FIG. 4, which is an alternate embodiment fromthat shown in FIG. 2, the base member 20 may be hollow, particularly ifit is desired that the base member shall be used to contain rechargeablebatteries or a transformer. Under such circumstances, as shown in FIG.4, the base member 20 will be formed of appropriate material to providesuitable strength and size to adequately contain said batteries and alsohave sufficient strength to support the tube 28 and the light shield 30on the lower end thereof in desired relationship with respect to thewater 14 normally confined within the sidewalls of the pool.

As best seen from FIG. 1, the tube 28 preferably is substantiallyL-shaped, whereby a normally upper, horizontal Shorter leg 32 issupported within a seat 34 which is formed within the upper surface ofthe base member 20 and is clamped therein by means of a clamping head 36which preferably has a complementary concavity 38 therein to receive thehorizontal portion 32 of tube 28 to secure the same operatively to thebase means 18. Appropriate wing screws 40 are threaded into suitabletapped holes 42 formed in the base member 20. Suitable openings inopposite sides of the clamping head 36 receive the screws 40 whichsecure the clamping head 36 in operative position with respect to thebase member 20 by fixedly positioning the horizontal leg 32 of the tube28 in operative position with respect to the deck and sidewall 16 of thepool 14. By removing wing screws 40, the light tube 28 may be removedand leave only base member 20, without any dangerous projections. Anoptional key 35 may also be included to resist rotation, as shown inFIG. 4.

In the preferred position of the tube 28 with respect to the base means18, the curved portion of tube 28 which connects the horizontal portion32 with the substantially vertical portion 44 thereof either engages orsubstantially engages the coping 12, for example, of the deck 10, so asto somewhat stabilize the position of the tube 28 with respect to thepool sidewall. It will be understood that the vertical leg 44 of tube 28extends downwardly into the body of the water of the pool a sufficientdistance to illuminate the body of the water, particularly when the poolis used in nighttime conditions. The lower end of the vertical leg 44 oftube 28 supports the light shield 30, within which an electric light 46and an electric socket 48 are mounted. As seen from FIG. 3, the electriclight bulb 46 is, for example, of the sealed-beam type, similar to thoseemployed in automobile headlights. Such illustration is not to beregarded as restrictive, however. The contacts of the bulb 46 arereceived within the socket 48 which is connected to appropriate wires ofan electric conduit 50 which extends upwardly through the tube 28 and,at the terminal end of the horizontal leg 32 thereof, are connected toan appropriate electric plug to which, for example, an electric socket52, of readily detachable type, is connected. Socket 52 is connected toone end of a short conduit 54, the other end of which is connected to asuitable outlet plug connected in circuit with a voltage transformerunit or battery 56. This is a convenience and safety feature, as whenchanging the bulb or removing the light for winter storage.

In accordance with the principles of the present invention, the voltagetransformer unit 56 is adapted to be connected by a conduit 58, forexample, to a suitable source of conventional household current, forexample, of 110 volts. If the unit 56 is a battery, it may be connectedto a suitable charger, not shown. The transformer unit 56 is adapted,for example, to reduce conventional household voltage to a relativelysafe range of approximately 12 volts, for example. However, suchreduction in voltage is not to be considered restrictive but onlyillustrative. Alternatively, household voltage, such as I 10 volts, maybe used ifa ground fault circuit interrupter (G.F.C.I.) is included inthe circuit for human safety purposes. Under conditions where thetransformer unit 56 is used, although illustrated in FIG. 1 as beingmounted directly within the deck 10, it is preferred for safety purposesthat such unit should be located at a remote location for as, orexample, within a residence or a garage where the source of thehousehold electric current is located and from which current is suppliedto the lighting system for the pool by a conduit leading to one or moreelectric outlets, of the outdoor type, adjacent or within the pool deck.I

It also will be seen from FIG. 3 that the shell 30, which may be formedfrom any suitable material such as non-corrodible metal, syntheticresin, or otherwise, is connected by a coupling 60 to the terminal endof the vertical leg 44 of the tube 28. Such coupling is of the typewhich will permit a limited rotation of the shell 30 about the axis ofthe leg 44 of the tube 28 and thereby permit appropriate orientation atinstallation. To provide further adjustment of the rays from theelectric bulb 46, a gimbal means can be used, as shown in FIG. 3A, inwhich said bulb fixed mounted preferably within a suitable bracket 62which, for example, may be in the form of a rim encircling the perimeterof the bulb 46. Said rim is connected at diametrically opposite pointsby means of pivot screws 64, to opposite sides of the shell Therefore,which is provided with a forward opening 66 through which the rays ofthe electric bulb 46 are sidewall Tl-Ierefore, it will be seen that theposition of the electric bulb 46 is adapted to be adjusted about both avertical, as well as a horizontal axis and thereby provide substantiallyuniversal adjustability of the light bulb 46 so that the rays from thelight bulb may be directed to any desired location within the body ofthe water in the pool 14. An alternate adjusted position of the lightbulb 46 is illustrated in phantom in FIG. 3A.

In the foregoing description, it has been indicated, as an alternative,that the base member 20 may be of a portable nature which has sufficientweight that the base member alone will position the light structure inany desired position with respect to the body of the pool. However, itis preferred that the base means 18, including base member 20, bemounted fixedly with respect to the pool, as shown in FIGS. 1 and 2. Forthis purpose, base member 20 is provided with suitable anchoring meanssuch as laterally extending bosses 68 having openings therein throughwhich suitable lag screws 70 may be extended for threading engagementwith appropriate sockets 72 mounted or otherwise formed within the deck10, for example. If desired, suction cups, not shown, may also be usedas an alternate securing means.

Referring to FIGS. 6-10, a different embodiment of swimming pool lightsystem is illustrated but the same employing similar basic principles tothe embodiment shown in FIGS. l-5. In the embodiment of FIGS. 6-l0, thebase means 74 essentially comprises a shell 76 and a cover 78. The shelland the cover may be formed from any suitable material such as by beingstamped from metal, molded from synthetic resin, or otherwise. Theprincipal purpose of the shell 76 is to contain weight-supplyingmaterial 80 as shown in exemplary manner in FIG. 9. Such material 80 maybe in the nature of sand, lead shot, or other appropriate material,including gravel or otherwise, or it may be a rechargeable battery 81,as shown in FIGS. 8 and 9. The purpose of the base means 74, in itspreferred embodiment, is to provide a storage box means to support thelight-supporting tube 82 which, as in regard to the tube 28 of theembodiment shown in FIG. 1-5, has a horizontal leg 84 and asubstantially vertical leg 85 which, on its terminal lower end, supportsa light shield 88.

It will be understood that the leg 86 of the tube 82 will besufficiently long invention shown permit the disposal of the lightshield 88 and the bulb therein, not shown, below the water level of thepool, as in regard to the embodiment of the inventionshown in FIGS. 1-5.Also, the shell 76 of base means 74 is adapted to rest upon surfaces ofthe deck 10, or upon the upper surface of the coping 90 thereof, if thelatter extends horizontally a sufficient distance to permit suchsupport. If desired, the lower surface of the shell 76 may be providedwith rubber or plastic buttons 92 which directly engage the uppersurface of the coping 10. If desired, however, in lieu of the buttons92, the same may be suction cups. Further, it is to be understood thatthe base means 74 may be disposed at any suitable location upon the deck10, for example, so as to dispose the curved portion of the tube 82, forexample, in engagement with the coping 90, if desired, or otherwise.

It also will be understood that the light shield 88 may be of a fiedtype, which contains a socket and an electric bulb therein, not shown,or said light may be of the type comprising bulb 46 and the supportingmeans shown in shell 30 of the embodiments illustrated in FIGS. 1-5, ifdesired. Further, the surface of the light shield 88, if desired, may beprovided with an abutment 94 which is adapted to engage the idewall 96of the pool, if desired. Similarly, in the embodiment shown in FIGS.1-5, the shell 30 also may be provided with an abutment 31, for apurpose similar to the abutment 94 of the embodiment shown in FIGS.6-10.

In order to secure the tube 82 and especially the horizontal leg 84thereof firmly with respect to the shell 76, for example, said shell maybe provided with a pair of transversely extending ribs 98 which areprovided with seats 100, see FIG. 10, which have complementary clamps102 adapted to overlie the seats 100 for the purposes of securing thehorizontal leg 84 of tube 82 in the operative position desired withrespect to the shell 76. Appropriate screws or bolts 104 affix theclamps 102 to the ribs 98.

The cover 78 may be of an appropriate esthetic design, as shown in FIG.10, for example, and the rim 106 thereof, for example, is adapted tooverlie the upper portion of the sidewalls of the shell 76, somewhat intelescoping manner. Also, adjacent sidewalls of the shell 76 and cover78 are provided with complementary notches 108, 110, as shown in FIG.10, through which the horizontal leg 84 of tube 82 extends.

Referring to FIG. 7, it will be seen that the electric conduit, notshown, which extends through the tube 82, terminates in an electricplug, not shown, mounted in one side of shell 76 with which, as shown inFIG. 7, an electric socket 112 connects. Said socket is connected to anelectric conduit 114, for example, having an end engageable with anoutlet socket of a voltage transformer unit 116, for example, which maybe mounted in the deck 10, or positioned otherwise, such as describedabove with respect to the voltage transformer unit 56 shown in FIG. 5.By such means, in the event the base means 74 should be accidentallykicked or otherwise dislocated from its normal position upon the deck10, for example, no damage will be sustained by the connecting conduit114 inasmuch as the socket 112 and the plug frictionally and slidablyengaged therein easily may be disconnected as a result of such movementof the base means 74.

Referring to FIG. 8, it will also be seen that if desired, the shell 76may be permanently located with respect to a deck 10, for example, orotherwiseadjacent the side of a pool. Such permanent connection may beac complished by means of appropriate lag screws 118, for

example, which may be threaded into appropriate plugs mounted orotherwise formed within the deck 10, for example. Although tube 84 isshown terminating within shell 76, it is to be understood that it mayextend beyond the shell and terminate with an electric plug which may beengaged by socket 1 12-, such as shown in FIG. 7.

In conjunction with or as an alternate light securing means, there isshown in FIGS. 1 and 3, a socket bracket 122 which is permanentlyattached to the sidewall 16 of a swimming pool by means of a bolt 124which is connected to bracket 122 and extends through a leak-preventing,yieldable gasket or washer 126 and also through a small hole in thesidewall 16. Suitable commercial folding wing-type anchor screws or wellnuts 128 are extended through the hole in the sidewall and then the bolt124 is rotated to draw the anchor screw or well nut tightly against theoutside surface of the sidewall. The light shield 30 is provided with aprong 130 which is slidably received in the socket of bracket 122 in amanner to effectively attach the light shield against accidentaldislodgement from the sidewall 30.

From the foregoing it will be seen that the present invention provides aplurality of embodiments of swimming pool light systems which may bemanufactured and installed at far less expense than the types ofunderwater lights now employed in masonry and other type pools of arelatively expensive nature. In effect, it is only necessary to drop thelights over the side of the pool, in accordance with the principles ofthe present invention, connect the electric conduit leads to suitablesockets provided either in underground wiring or other similar meansprovided adjacent the sides of a pool. If the socket bracket 122 andprong 130 type of connection is used, the same are easily coengaged,incident to mounting end 32 of tube 28 in base 20.

If desired, the conduit between the voltage transformer or battery units56 and 116 and/or the source of conventional household current may beprovided with a master control switch, not shown, which may be mountedwithin a residence, garage, or otherwise. Due to the fact that theportions of the lights which are disposed below the water level of thepool are only supplied by a battery or current of low voltage value, orinclude a ground fault circuit interrupter unit, if conventionalhousehold voltage is used, there is no reasonably possible source ofdanger to be sustained by human beings using the pool. This is dueprimarily to the fact that the resistance of water to the passage ofelectric current thereto is so much greater than the resistance offeredby copper wires, for example, such as used in the conduits of bothsystems of the invention, that electric current will travel along thewire rather than through the water. Thus, due to this fact, as well asthe low voltage, substantial safety is provided bathers using such anilluminated pool.

By way of further example, it is apparent from the foregoing descriptionand the drawings comprising a part thereof that the light systemsembodying the principles of the present invention readily may be mountedat suitable locations around the sidewalls of a pool,

and, for example, especially adjacent a diving board which may beassociated with the pool. For example, one of the lights may be mountedadjacent the sidewall immediately beneath such diving board and therebyilluminate the area of the water into which a diver will projecthimself. Similarly, one of said lights may be positioned adjacent stairsor other appropriate means by which a bather either leaves or enters apool.

As a further convenience and safety feature, the embodiment of theinvention illustrated in FIG. 7, for example, may have a battery 81,such as shown in FIGS. 7 and 8, mounted within shell 76 and enclosed bycover 78, and element 116 shown in FIG. 7 may be a battery chargerconnected to a source of charging current such as household voltage.Also, the charger 116 may have a suitable two-way switch 117 connectedin the circuit of charger 116 by which, when the switch is in centerposition, for example, the lights are off; when the switch lever ismoved to one side, the battery is connected to the lights to energizethem; and when the switch lever is moved to the opposite side, thelights are off and the battery is connected to the charger and thecharger is operating to charge the battery.

As an alternative to the foregoing arrangement of switch 117, a specialreceptacle, not shown, can be used by which, when the lights are off,the battery is being charged by the charger and when the lights are on,the battery is not being charged.

While the invention has been described and illustrated in its severalpreferred embodiments, it should be understood that the invention is notto be limited to the precise details herein illustrated and describedsince the same may be carried out in other ways falling within the scopeof the invention as illustrated and described.
